Most Common Savanna Plants Overview

Savannas are vibrant biomes bursting with diverse plant life and wildlife. Predators and mammals usually steal the limelight, but trees, shrubs, and flowers offer essential sustenance for herbivores and give the savanna its unique character.

Savannas, also known as tropical grasslands, are marked by extended dry periods followed by inconsistent rainy seasons. The biome’s divisions, based on dry season duration, vegetation, and specific patterns, can sometimes blur lines among ecologists. A notable characteristic, however, is the vast grass-covered terrain punctuated by occasional trees.


Savanna Biome Overview

  • Definition: A grassland biome with extended dry seasons followed by inconsistent rainy seasons. It features grassy plains with occasional trees.
  • Characteristics:
  • Two seasons: wet and dry, each spanning around six months.
  • Dominated by perennial grasses.
  • Average temperature: 68-86°F (20-30°C) in dry season, 50-68°F (10-20°C) in wet season.
  • Frequent bushfires during dry periods.
  • Plants possess unique adaptations for survival.
  • Location: Mainly between 8° to 20° from the equator, covering large parts of Africa, Australia, India, and South America. Temperate grassland counterparts are in North America, Russia, Argentina, Uruguay, and South Africa.

Key Plants in the Savanna

Grasses

Savanna grasses, integral to the vast landscapes stretching across continents like Africa and Australia, play a pivotal role in these ecosystems. These grasses, often tough and resilient, have evolved unique adaptations to thrive amidst the challenges of extended dry spells and sporadic rainfall. Notably, the Bermuda Grass, with its low-growing yet hardy nature, can recover rapidly following droughts or even after grazing by the region’s prolific herbivores. On the taller side, Elephant Grass stands out, often reaching impressive heights, serving as a vital food source for elephants and other large mammals. Its deep-rooted system ensures survival even in nutrient-depleted soils. Additionally, the Red Oat Grass, prevalent in regions like the African savanna, is a prized resource for pastoral communities, nourishing livestock with its protein-rich blades. Beyond providing sustenance to a myriad of herbivores, these grasses also play a role in mitigating soil erosion, maintaining soil fertility, and acting as fuel for the periodic bushfires, which, in turn, rejuvenate the landscape. Through their enduring presence and adaptability, savanna grasses underline the intricate balance and resilience of one of the world’s most iconic biomes. Below is a summary of the typical grasses found in the Savanna.

Trees

The vast landscapes of savannas are punctuated by the striking presence of its trees, which rise majestically from the grassy plains and tell stories of resilience and evolution. The iconic Acacia trees, with their unique silhouettes and formidable thorns, not only provide shade and refuge for many savanna dwellers but also exhibit remarkable adaptability with their deep-rooted systems drawing moisture even in the driest periods. The Baobab, often dubbed the “Tree of Life”, stands as a testament to time, with some specimens believed to be over 2,000 years old. Its gargantuan trunk, which can store substantial amounts of water, ensures its survival during extended droughts. Another notable member of the savanna tree community is the Jackalberry Tree, providing a bounty of fruits that sustain a myriad of wildlife from birds to mammals. Its relationship with termites offers a fascinating glimpse into the intricate web of symbiotic relationships in this biome. Moreover, the sporadic placement of trees across the savanna plays a crucial role in biodiversity, offering habitats, food sources, and vital shade. These trees, in essence, are nature’s pillars in the savanna, symbolizing endurance, diversity, and the delicate balance of life. Below is a summary of the typical trees found in the Savanna.

Tree NameCharacteristics
AcaciaEmblematic savanna tree; has sharp spines and toxic tannins.
BaobabCan store vast amounts of water; has existed for over 2,000 years.
Jackalberry TreeProduces edible fruits; has a mutualistic relationship with termites.

Shrubs

Savanna shrubs, often overlooked in the backdrop of towering trees and expansive grasses, offer a unique tapestry of diversity and adaptability. These tenacious plants, typically shorter and bushier, are evolved to withstand the intense heat and irregular rainfall synonymous with the savanna biome. The Sickle Bush, with its spiny branches and feathery leaves, showcases nature’s blend of beauty and defense; its pendulous flowers attract pollinators while its thorns deter herbivores. Another captivating shrub is the Buffalo Thorn, growing strategically near seasonal riverbeds. Its distinguishing zigzag twigs and dual spines reflect a blend of aesthetic allure and survival tactics. The Raisin Bush, aptly named for its fruit resemblance, flourishes near water sources, providing bursts of color during its flowering season, much to the delight of pollinators and onlookers. These shrubs, often armed with spines or toxins, not only deter herbivores but also provide food, shelter, and nesting sites for a myriad of creatures. By anchoring the soil and acting as windbreaks, they play a subtle yet vital role in the savanna’s ecosystem dynamics. In essence, savanna shrubs encapsulate the resilience and versatility required to thrive in one of Earth’s most challenging biomes. Below is a summary of the typical shrubs found in the Savanna.

Flowers

Amidst the vast stretches of grass and interspersed trees, the savanna’s flowers emerge as delicate bursts of color and life, defying the biome’s harsh conditions. Their existence in such a demanding environment is a testament to nature’s ingenuity. The Heath Aster, a proud member of the sunflower family, stands out with its vibrant yellow blossoms, primarily in the fall. These flowers not only add aesthetic beauty but also attract various pollinators, enhancing biodiversity. The Euryops, with nearly 97 species, adds a touch of wonder with its low-lying blooms from fall to winter. Its name, derived from ancient Greek, mirrors its captivating appearance, translating to “wide eyes.” Another notable flower is the Great Blue Lobelia. Its exquisite blue petals, which come alive between July and September, are a favorite among bumblebees and hummingbirds. Beyond their visual appeal, these flowers have evolved impressive adaptations, from fire resistance to specialized seed production, ensuring their continued presence in the savanna. They not only contribute to the savanna’s ecological balance but also serve as a reminder of the fragile beauty persisting amidst the ruggedness, enriching the biome with color, diversity, and vitality. Below is a summary of the typical flowers found in the Savanna.

Other Tropical Plants

The savanna, while primarily recognized for its vast grasslands and iconic trees, also houses a fascinating array of other tropical plants that have carved out a niche in this transitional biome. The Palmyra Palm, for instance, stands as a testament to adaptability. Belonging to the Borrasus genus, this plant thrives in both tropical and subtropical conditions, its fruits encased in a tough fibrous tissue that shields them from potential predators and the environment’s extremes. Another intriguing resident is the Candelabra Tree, which, despite its cactus-like appearance, belongs to the euphorbia family. It uniquely exhibits photosynthesis directly on its stem, bypassing the need for traditional leaves. Then there’s the Lemongrass, which flourishes in the wild expanses of the savanna. With aromatic leaves that naturally repel insect herbivores and robust roots anchoring it firmly to the ground, this plant epitomizes resilience. These tropical plants, by bridging the gap between desert and temperate biomes, enrich the savanna with added layers of complexity and beauty. Their distinct adaptations and survival strategies underscore the savanna’s rich tapestry of life, reflecting nature’s boundless creativity in ensuring survival amidst challenging conditions.
